No. Yes. No. Yes.
(There are windows utilities that can format an SD card and write SD images.)
Really, that link referenced earlier said specificly there wasn't. *kicks the internet for lieing to me*
Well, i'm going to do it on the linux machine anyway since it is a faster down load.
Does the V2 img contain the correct chainminer? or does that need to be downloaded too?
your original image should have the v2 miner on the card at /opt/bitfury/chainminer_v2_M_board
you can just run the "miner" program in there or if you want you can update the source (git pull;make) then run with the latest code.
no need to make a new image.
